What is a good amp that cost no more then 3500.00

Proac Response 2.5 and i am going to keep it for awhile along with my future. My room is 156 (13ft) X 204 (17ft).
My preamp is a Yamaha DSP-AX1 same as the RX-V1 but it is a a/v amplifier.

Are you looking for a 5 channel amp to match the Yammie? If you are using the Yammie as a pre for music, I would suggest getting a used 2 ch pre and a used amp. Putting about equal $ into each piece (1500-1750 each)would give you much better 2 channel sound than a really great amp with the Yamaha as a pre.

KRELL FPB300 can be found occasionally for as low as $3300. The FBP200 can be found more easily in your price range, but many people feel the 300 and 600 are better choice for sound quality.

Good luck.

You should spend $2000 on an amp and use the other $1500 to buy a good used preamp, you definitely need to upgrade from Yamaha. Maybe a good solid state amp like an Ayre or M-L, or BAT, and a tubed preamp such as a BAT 51.

Buy a musical fidelity M3 integrated it kills every amp here except the pass x250 maybe and it has a lot more power and a really good preamp to boot. Lastly it is much much better than the A3cr, believe me i've owned both.
